Thank you Doug!

This is a great suggestion and will prevent me from getting lost in the different analyses. And it will also offer the opportunity to analyze subjects from the two different cohorts together without coping the data in one SUBJECTS_DIR.

Thanks again!

Best regards, Katharina

Hi Katharina, is there really a problem with the output going into the SUBJECTS_DIR? If so, you can create a separate SUBJECTS_DIR for each project. Inside of each SUBJECTS_DIR you can then create a symbolic link back to the original SUBJECTS_DIR, linking only the subjects you want in that project. The symbolic link is not a copy of the data, just a pointer, so you'll maintain a single copy. doug

Dear FreeSurfer users,

we started to analyze structural MRI data from two large cohorts (one with over 2100 and the other with over 1100 subjects). Preprocessing is completely done for all datasets and I've worked myself through this Qdec tutorial (http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis). Everthing works fine but I would like to organize the output of qdec project-wise and not all together in the qdec folder in the subject directory. This is important because the qdec.table.dat file would be quite different for the various projects.

Is there a way to organize the output like this: /project_1/analysis_1 ... /project_1/analysis_n

/project_2/analysis_1 ... /project_2/analysis_n

...

and the corresponding qdec.table.dat file in the project_x folder?

I tried to run qdec with a qdec.table.dat file saved in another folder but the output is still saved in the subjects dir qdec folder.

I would be very grateful for any hint or comment on this topic.

Thank you in advance! Best regards, Katharina _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
